6.5.4 Connecting power cables
① Contact surface
② Cable clamp
Figure 6-5 Example: Connecting the power cables
1. Clean the contact surfaces ① immediately before screwing the connections. Use spirit and
a lintless cloth for cleaning.
2. Apply a thin film of grease. Electrolube 2G is a suitable lubricator.
3. Screw the cable lug with a M12 screw and, if necessary, with a washer to the contact
surface. Tighten the nut (torque: 50 Nm).
4. Remove the cable shield. Fasten the cable with cable clamps ② to the cable support trail.
6.5.5 Connect the power cable to the motor and the supply system
When connecting the cables, observe all the conditions regarding conductor protection. Do not
exceed the permitted cable lengths between the converter output and motor. The distance
between the motor cable and the signal cable should be at least 20 cm. Do not lay grid-side and
motor supply cables in parallel to each other.
The positions of the connections are shown in the layout diagrams. Detailed wiring notes for the
converter are contained in the circuit manual of the converter.
